Patented Mar. 12, 1935 NITE srATE's PATENT OFFlCE LIGHTING FIXTURE 7 Henry DOlier, Jr., BridgeporLConn. Application July so, 1932 Serial No. 626,608 5: Claims. (o1. 240- 6) My invention relates to' lighting fixtures, es-

pecially to the assembly of parts for lighting fixtures held in alignment. I 1

The control of light distribution by reflec- 5 tors'when assembled with sockets, wireways and other lamp accessories has been common practice for years. As more light from rows of lamps is now popular, the inventor shows standard accessories quickly and inexpensively put 1 together by means of novel features so as to hold lamps, sockets, wireways, and reflectors in alignment forming one unit.

In the drawings in which my invention is illustrated:

15 Fig. 1 is a row reflector with wireway and sockets. I

Fig. 2 is a row reflector as in Fig. 1 with the wireway removed.

Fig. 3 is a row reflector with wireway and 20 sockets in different arrangement with cut away sections showing sliding clamps and socket bushings.

Fig. 4 is an assembly of wireways and sockets with individual reflectors, one reflector in as- 25 sembled position and one reflector detached.

The elongated hole allows change of angle position.

Fig. 5 is an assembly of sockets and sectional wireway with additional wireway removed.

30 Fig. 6 is a cross section through the holding screw, sliding clamp, socket base and; wireway.

Fig. '7 is a full size isometric drawing of a sliding clamp. The holes are threads.

35 Fig. 8 is a cross section of sliding clamp, holding screw, socket base and channel, used in place of wireway.

Descriptions below apply to similar numerals in every case in which they are used.

40 Fig. 1 is supplemented by Fig. 2, Fig. 4 is supplemented by Fig. 5, both Fig. 2 and Fig. 5

have the elongated grooved wireway omitted to expose details of the clamp plate 4 held and adjusted by screws 5 to set tight the plate 4 in the grooves of a wireway for rigid assembly.

Fig. 6, Fig. '7 andFig. 8 are supplementary figures detailing clamp plate 4.

Figs. 1, 2 and 3 show a standard angle socket '7, the angle nozzle at one end of socket '7 has 50 an internal thread into which engages the threaded flange bushing 6, the flange of the bushing 6 on one side of a hole with the threaded nozzle on the other side allows the flange to clamp the nozzle, rigidly positioning the socket 55 7 when the threaded bushing is screwed as far as'possible into the socket nozzle. The inside of bushing 6 is smooth for a wire passage into the socket where contact is made with the socket terminals in the usual manner.

Standard socket 8 in Fig. 4 has a base 9 and 5 cover 10, the cover 10 is held in position'by the threaded insulating ring 11 engaging the threads of socket 8. The reflector 12 with the opening for passing a couple of threads of the socket 8, is held in position when clamped between the 10 cover 10 and the threaded flange insulating ring 11. From cover 10 to cover 10 of sockets are sections of wireway 13 fitted in the conventional manner as is common practice, these assem-v blies are fastened to a wall or ceiling surface for 5 support as the sockets are generally spaced feet apart, the covers 10 and section of wireway 13 provide a free passage for the current wires to pass through for socket connection. It sometimes becomes necessary to install lamp sockets close spacing (inches apart) without the wall or ceiling surface for fastening, therefore the applicant makes possible a rigid assembly in alinement by adapting the novel method of a clamp plate 4 projecting from the base 9 of socket 8 with screws 5 for holding and adjusting the clampin the grooves of an elongated wireway 2 with grooves 3. The wireway 13 furnishes area for current carrying wires while the grooved wireway '2 furnishes assembly support and additional area or space for added circuits which is necessary on account of the greater number of lamps to be provided for when the sockets are spaced inches apart.

' Row reflector 1, with wireway 2, having side grooves or channels 3, in which slides sliding clamp 4, held by screws 5. When screws are set tight, the sliding clamp 4 clamps on the lower edge of grooves or channels. Threaded bushing 6, holds angle sockets '7. Socket 8, base of sock 40 et 9, sectional wireway 13, are common articles in the trade assembled in the conventional manner. Socket porcelain flanged ring 11, passes through elongated opening 14, in individual reflector 12, to hold the reflector in position. Channel with grooved side 15, replaces wireway 2, when wireway is unnecessary. 7

My invention shows an assembly of reflectors, sockets and wireways allowing for standard electric wiring and connections. InFig. 1, Fig. 2,

and Fig. 3, the wiring is placed and connected in the usual manner after which the wireway 2, with grooved sides 3, is fitted over sliding clamp 4, and. when in position the screws 5, are set and hold the assembly in rigid alignment. The

sockets 8, carried on bases 9, are assembled by sectional wireway 13. The sliding clamps 4, are held by screws 5, through socket bases 9. The Wireways 2, or grooved channel 15, is fitted over the sliding clamps 4 and when the screws are set tight, the assembly is held in rigid alignment. In Fig. 8, a channel 15, is shown in place of wireway as shown in Fig. 6, as the sectional wireway 13 will be adequate for some wire capacities.

I claim:

1. An elongated grooved channel member, a lighting unit comprising a reflector, socket and lamp adjustably mounted adjacent to said channel, said unit carrying a plate adapted to slide in the grooves in said channel, adjusting means securing said plate to said unit whereby the plate can be clamped rigidly in said channel and secure the parts in adjusted position.

2. A lighting unit comprising a socket and a reflector; a grooved, elongated channel wireway adjacent said unit; a plate clamp projecting from said unit, and slidable in the groove of said wireway; means to rigidly clamp the plate in the grooves of the wireway to secure the parts in position; an elongated hole in said reflector, and means extending through said hole to secure the reflector to said lighting unit in adjusted position.

3. A lighting fixture comprising a reflector, a side-grooved. channel wireway adjacent said reflector, a plate clamp adjustably secured to said reflector and slidable in the grooves of said wireway, and clamping means to rigidly secure said plate clamp to said wireway.

4. A lighting fixture including a socket, a side grooved channel wireway, a clamping plate secured to said socket, and slidable in the grooves of said wireway, and screw means for rigidly clamping said plate in said grooves in adjusted position.

5. A lighting unit comprising a grooved channel wireway, a reflector, a socket and a lamp, an adjustable clamping plate secured to said reflector and slidable in the grooves of said wireway, and means to clamp the plate in the wireway, whereby the various units are held in assembled position.
